1.129428 Specification of Letters 1" e i Applieetion filed October 218. 13..

To all whom may com? it known that i, BURY, a citizen of the I. L resident of Milui-iukee. in the eeuuty Milwaukee and. State of ll isi'ionsin, have in vent-ed new and useful improvements in Carbureters, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

. This invention has for its object to provide a carburetor partieula'rlg, designed for an engine-driven centrifugal separator, but capable of general use.

An object of the invention is'to provide a carburetor of minimum size by providing the float with a eounterweight to :1 st it n closing the gasolene supply valve.

Another object of the invention is to provide a carburetor having a gasolene supply tank mounted thereon and directly conimuniczttiug therewith hut (letael'iahle anti provided with a valve for ole-sing the con inunicatiou when it is to he iletacheiii.

Another object oi the invention is to Silliplify the construction of a (ia huroter whereby it may lie inexpensive to manufacture and durable and eiiieient in use.

"With the above and other objects in View the invention consists in the (-urhuri-et r as herein claimed and all equivalents.

Referring to the acriunpanving (lruuings in which like eliaractrrs of reference indicate the same parts in the ilili'ereut views: Figure. 1. is a sectional elevation ot :a earhureter constructed in iu'roriiauee invention; and Pie. i? :1 plan view there of with the. gasolene .lllrply tank ron'ioved.

in these drawings iniilia'ai'es a cupshaped limit ohaiulwr n'hiezh is preferably formed integral with an intake pipe 1 for connection with the intake port of a gasolone engine or the like 12 lwing: an ordiizarv throttle valve in the intake pipe ha ing a connection 13 with a governor or other con trolling (ievire not shown. A. email float 1 is contained within the float chamber 10 amt has a pointed stem 15 at its upper end which forms a. needle valvefor controlling the inflow of gasoleno through a valve seat 16 in the bottom ol :1 gasolene supply tank 17. Though the float may be of suilicient size to etl'ect the control of the flow of gasolene into the float. chauil'ier without asfiistancm it is preferred to re-tluce the oi perte to with this poi-rim, heloi-v ii and a 5913! 18 whieh pivot;- inoimted on the float chaint r 1Q andv thereof has hook-shaped inner end ing the stem 15 at its reduced portion anal. also has a weight 19 on its outer end which serves to counterbulanm-i the Weight ofthe float and render it more sensitive to the influence of the change of gasolene level within the float chamber.

The limitchamber has an inclined outlet duct 20 lenziing from the bottom thereof to the interior oi tlu take pipe 11 and its upend whieu i htiv ehovo the normal oi" 5;: eo ei 'iioat ehauiher is controlleti. or i needle use 'lho valve seat i6 :5 contained Within the gasoieue supply taint 2.? with a shoulder hearing on the bottom thereof and it threadef cn il projeetine; th ough the bottom of the tanln and a, disk .3 threaded on the pro jecting end of the vaive seat and is preferably soldered to the bottom of the gasolene sup y tank as Well to the threaded end oi (l alve seat. This (lisk 22?- is threadoil within the upper end of the float chamber it) lo ei'mstitute the supporting connection for the supply tank permitting it td'be readii tietzlched whenever desired.

valve stem is leek-ably provided with its lower end threaded in the upper portion of the valve seat 16 and forms a needle. valve for closing the valve seat from aliove eahi valve stem projectii'ig through the upper eiui of the gasolene supply tank and provided with a head 24 by which it may he turned. 'A stop is mounted on the gasolene supply tank to engage the head 24 and prevei'it its accidental removal.

in operation the gasolene is free to flow from the gasoline supply tank through the alve seat in the bottom thereo'i into the float ehumhe-r from \vl'iieh it may be drawn through the duet 9O hv the suction from the engine in the intake pipe 11. The normal level of QflSHlPIlC Within the float chamber is maintained just below the level of the outlet of duct so as not to overflow by the lioat 1% rising "with the assistanceof the eounterholenee l9 and el'ieeking the ini'hinv mowing through Ft slot in the upper edge of g2 ifi Jll'lne by closing the valve the val e stem 15. means of L. 5 e01; balance 19 a smaller float and Jen equ y a. smaller float chamber may be emple yecl than would be necessary the float alene wem (T-"(ll upon,

The a.solene supnly reservoir being invented. directly on the float chamber is readily detachable for inspecting the parts, and a loss of gasolene through the valve seat at such times is prevented by clas said valve seat by means 0f the valve The lever 18 being pivotelly aoumtecl by means of a cotter pin is readily rememale when it is desired to remove the fleet.

The carbureter sf this invention is tremely simple and inexpensive in its eonstruction and durable am} eilieient in its operation.

What I claim as new and esire to secure Letters Patent carbureter, eemprising a float chamber l i-Wing an outlet duct, a fleet contained 'thin the float chamber, valve member the float, a. gasolene supply tank y mounted on the fleet chamber, a in the bottom thereof through is admitted to the float eiiztm'oeln falve seat being engaged by the valve member, and an independent needle valve carried by the detachable gasolane supply tank for closing the valve seat.

In testimony whereof, I will); my signa, ture, in 'presei'zee of two witnesses.
